(Cl. 308-59) This invention is an adjustment means for bearings, and while it is susceptible of general sleeve or yoke 16 at its upper end. supports the journal 5 of the roller. This yoke use Where the adjustment of certain types of bearings is required, it is adapted particularly for J5, use in connection with printing or lithograph presses. “An important object of the invention is to The means for adjusting this standard longi tudinally within its opening or recess includes a threaded pin or screw I1 passing through a suit- ‘52 able internally threaded opening in the base of the block and parallel to the bolt l2. The opening provide means of simple construction, for accurately and minutely adjusting the bearing spin10 die of a roller or shaft and locking the bearing for this screw or pin communicates with the re cess or opening I4 near the lower end thereof, _ and the inner end of the pin or screw is beveled, l0‘ securely in such adjusted position. tapered or inclined as indicated at Hi.

Operation of this bolt is carried out by means of the head l3, and it is apparent that rotation of the bolt will cause the block to move upon the projection H depending shown in the present illustration, it will be under stood that the mechanism here described will be duplicated at the opposite end of the shaft.

When the desired ad justment has been made, rotation by a suitable tool of screw '23 causes the beveled end thereof to engage behind plug 20' and force the same into engagement with the side of screw ill, thus hold 10 ing the latter securely against rotation in either direction. The range of adjustment of standard 55 may be increased or diminished by adjust ment of the screw I9 in the lower end of the standard. The ends of the plug 2%’ may be bev 15 eled as shown in Figure 4 to‘ insure proper co operation between the plug and the locking screw 23 and also to insure proper locle'ng en gagement between the plug and the screw H’. From the foregoing, it is apparent that adjust 20 ment of the shaft 5, either axially or radially may be quickly and easily made. Rotation of bolt I2 in the proper direction will cause the plug and its shaft supporting yoke to move in such direction as will secure axial adjustment of the roller, while 25 operations of the screw or pin l'l secures the proper vertical adjustment of the shaft. By ar ranging the adjusting screw and the lock therefor in the manner shown and described, ready access for these adjustments may be had from the side 30 of the machine and without necessitating stop ping or slowing down of the machine during such operations. What I claim is: 1. In a bearing adjuster, a block, a bearing 85 standard slidable in said block, a screw in said block, the inner end of said screw tapered and engageable with a surface of saidstandard, where by movement of the screw will be transmitted to said standard, a locking plug in said block adapted 40 to engage a side of said screw, and a locking screw in said block parallel with said ?rst men tioned screw, said locking screw having an in clined inner end to engage and move said plug. 2. In a bearing adjuster, a frame, a block, a bolt in said frame engaged in said block, said block having an opening therein, a standard slidable in said opening, a screw in said block having a tapered inner end, said end projecting into said opening and in engagement with the lower end of said standard, said block having a passage communicating with one side of said screw, a locking screw in said block in spaced parallel relation with said ?rst mentioned screw and having a tapered inner end, a plug slidable in said passage, the tapered end of said locking screw engaged behind said plug, whereby movement of said locking screw in one direction will move said plug into engagement with said ?rst named screw. 3. In a bearing adjuster, a block having an 15 opening, a bearing standard in said opening, a screw disposed axially in the lower end of said standard, a beveled head on said screw, said block having a lateral opening disposed at substantially right angles to said standard and communicating with the lower end of the opening therefor, and "1e inner end of said screw being tapered and en gaged with the beveled head on said ?rst named screw. 4. In a bearing adjuster, a support, a bearing 25 slidable in said support, an adjusting screw in said support for moving said bearing, a locking plug in said support for engagement with said adjust ing screw, and a locking screw in said support in spaced parallel relation to said adjusting screw 30 for moving said plug into engagement with said adjusting screw. 5. In a bearing adjuster, a bearing support, a standard slidable longitudinally in said support, a bearing on said standard, an adjusting member in 35 said support disposed parallel with said bearing and adapted to move said standard, a locking plug in said support adapted to engage and lock said adjusting member, and an operating element in said support disposed parallel with said adjusting 40 member for moving said plug.
